摘要:
Immunocompromised rodents that have been modified to express a fluorescent protein in substantially all tissues are described. These rodents are useful as models for gene expression, tumor progression and angiogenesis. Also provided are model systems where heterologous tissues fluorescing in a first color are transplanted into hosts that have been modified to fluoresce in substantially all tissues with a second color.
摘要:
Living cells can be stably modified to emit different colors from the cytoplasm and nucleus, thus permitting analysis of the status of said cells and the effect of agents on said cells either by visual or instrumentally-aided observation. These observations may be made, if desired, in real time. In addition, rates of proliferation and drug sensitivities can be determined in vitro in real time by the use of cells modified to express a single fluorescent protein and observing fluorescence intensity as a function of time.
摘要:
The disclosed invention relates to the observation that nestin expression is a marker for endothelial cell proliferation. Nestin expression is particularly useful as a marker for angiogenesis, particularly for tumor-related angiogenesis. Specifically, nestin serves as an excellent endothelium marker for brain tumors such as gliomas, hemangioblastomas, Schwannomas, medulloblastomas, and meningiomas. Accordingly, the disclosed invention relates to the use of this marker as a basis to model angiogenic activity.

Bacteria that are auxotrophic for at least two amino acids found in at least one tumor are effective anti tumor treatments, labeling agents, and vaccines against infection. Improved antitumor effects can also be provided such strains by passage through an appropriate tumor model.

摘要:
An application programming interface is provided by an operating system that includes a direct composition engine. The composition engine maintains a data structure that represents the display objects to be rendered on a desktop display. The application programming interface allows an application to write data to the data structure to update the display object, such as a window, for the application. Thus, multiple applications can update their respective display objects in this data structure. The direct composition engine is an operating system level process, presented to user-level processes as a service of the operating system. By having an operating system level process, performance standards can be maintained. The application programming interface also allows applications to provide display information that can be rendered more efficiently by the operating system than by the application.
